Bug Description

When testing upgrading nova packages from Rocky to Train the following issue occurs:

versions:
oslo.config 6.11.2
oslo.concurrency 3.30.0
oslo.versionedobjects 1.36.1
oslo.db 5.0.2
oslo.config 6.11.2
oslo.cache 1.37.0

Happens here https://github.com/openstack/oslo.db/blob/5.0.2/oslo_db/api.py#L304
where it register_opts for options.database_opts

This cmp operation: https://github.com/openstack/oslo.config/blob/6.11.2/oslo_config/cfg.py#L363

If I edit above cmp operation and add print statements before like this:
    if opt.dest in opts:
        print('left: %s' % str(opts[opt.dest]['opt'].name))
        print('right: %s' % str(opt.name))
        if opts[opt.dest]['opt'] != opt:
            raise DuplicateOptError(opt.name)

It stops here:
$ nova-compute --help
left: sqlite_synchronous
right: sqlite_synchronous
Traceback (most recent call last):
....same exception

Some import issue in nova?

Removing @db.select_db_reader_mode decorator from from _db_service_get_by_compute_host and _db_service_get_minimum_version in in nova/objects/service.py makes "nova-compute --help" work.

You meant it could be an import issue on the nova side?

Could be yes, but I don't know. Given that nobody has hit this before makes me think it's a dependency issue but which one is the big questions :)

Think this isn't a bug but was related to SELinux. This issue happend when I upgraded nova on our compute node and then this occured. So I removed the @db.select_db_reader_mode decorator usage in nova/objects/service.py to make it start.

I then proceeded to upgrade Neutron and Ceilometer on the compute nodes, Neutron requires the following SELinux packages to be updated in order for it to work:

libselinux libselinux-python libselinux-utils selinux-policy selinux-policy-targeted

When I upgraded that, neutron and ceilometer I didn't bother testing again.
I removed the commented decorators now and restart nova-compute and it worked.

The possibility of any of the additional packages after nova-compute there fixed it is very low.

The only thing I did manually except for that was to upgrade the SELinux packages mentioned above because that's required by Neutron.
